An Approach to Induction Motor Synthesis

A design method for induction motors, based on the use of a newly developed relation between the D2L of the rotor and all normal customer and NEMA (National Electrical Manufacturers Association) specifications except temperature rise is described. In developing this relation an equation-giving motor torque in terms of motor dimensions is given. This is of special interest since it does not involve equivalent circuit parameters. The equations are found to give accurate results.
